CONAP-301093：在e0M的高利用率期间显示SwitchUnachable_Alert、SwitchSNMPCommunication警报、SwitchInfoUpdateFailure_Alert
问题描述
- ONTAP以太网交换机运行状况监控器(CSHM)针对以下各项发出部分或全部警报：SwitchUnachable_Alert、SwitchSNMPCommunication _Alert和/或SwitchInfoUpdateFailure_Alert
- 如果为CSHM启用了SNMPv3监控、则两个交换机都会显示messages.log中的以下"FORed"消息"FORed"。示例：

- 从e0M ifstat输出中、我们可以看到接收和传输的大量"意外"流量。示例：
